If Epic had made a good sequel to UT99 and UT2k4, it would not have failed this drastically. That it has failed demonstrates enough that it's a poor game.
Yes, but during UT3's development Gears Of War was circumventing around it. Gears of War has already been said by Epic that its their #1 Priority, and is there new AAA series. UT3 simply had less focus and attention than most of the previous UT's have had due to Epic's change in favoritism towards a particular game series based on success. Gears of War gets the AAA attention now while UT is a secondary game, started since UT3 Development and GoW Debut Success.
